Abstract: The present disclosure discloses example random access methods and apparatuses. One example method includes a terminal receiving a random access configuration from a network device. Indication information from the network device is received by the terminal, where the indication information determines a target random access configuration in the random access configuration. Random access to the network device is initiated by the terminal based on the indication information by using the target random access configuration.

Abstract: A first terminal obtains a first transmission resource that is sent by an access network device and that is used by the first terminal to send data on a sidelink, where the sidelink is a wireless communication link between the first terminal and a second terminal, and the first transmission resource is a resource of an unlicensed spectrum. The first terminal performs a channel access procedure on the unlicensed spectrum. The first terminal sends first information to the access network device when the first terminal determines that a failure occurs in the channel access procedure performed on the unlicensed spectrum, where the first information is used to request to allocate a second transmission resource to the sidelink of the unlicensed spectrum.

Abstract: This application provides an example sidelink transmission resource configuration method. Each piece of sidelink data corresponds to one transmission requirement. After obtaining a first data, a terminal device determines a transmission feature of the first resource, and determines, depending on whether reliability of the first resource meets a reliability requirement of the first data, whether to send the first data by using the first resource.

Abstract: This application provides a method including: determining, by a terminal device from at least one radio interface technology, a first radio interface technology used to send first information, where each of the at least one radio interface technology corresponds to an uplink resource, and the first information includes a size of to-be-sent data of at least one logical channel of the terminal device; and determining, by the terminal device based on the first information and attribute information of the first radio interface technology, whether to cancel the first information that is in a triggered state, where the attribute information of the first radio interface technology includes a priority of the first radio interface technology or an uplink resource corresponding to the first radio interface technology. The method provided in this application improves accuracy of canceling the first information that is in the triggered state, and shortens a data sending delay.

Abstract: A base station configures, for a terminal, a contention-free random access resource for a beam failure recovery request. After determining that a beam failure has occurred, the terminal performs random access, and retains the contention-free random access resource after the random access succeeds, so that a beam failure recovery latency and signaling overheads can be reduced.

Abstract: A counting method and an apparatus are provided, and are applied to a carrier aggregation scenario of a first cell and a second cell. The method is: obtaining, by a terminal, a subframe K1 of the first cell and a subframe K2 of the second cell; determining, by the terminal, a PDCCH subframe from the subframe K2, and determining a monitoring subframe from the subframe K1 and the subframe K2; and controlling, by the terminal based on the PDCCH subframe, a DRX timer to perform counting, and monitoring a PDCCH based on the monitoring subframe to learn of arrival of downlink data and/or uplink grant, where the first cell is a cell on which idle channel detection needs to be performed, and the second cell is a cell on which no idle channel detection needs to be performed.

Abstract: A method for blindly detecting a physical downlink control channel and an apparatus are provided. The method includes: obtaining, by user equipment UE, configuration information sent by a base station, where the configuration information indicates a first cell in which downlink control information DCI does not need to be blindly detected and a second cell in which the DCI needs to be blindly detected in serving cells corresponding to the UE; and receiving, by the user equipment, the DCI sent by the base station in the second cell, and performing uplink transmission in the first cell based on the received DCI. The solution provided in the present disclosure resolves a prior-art problem that a quantity of PDCCH blind detections in an LTE system increases, and consequently hardware capabilities of many UEs cannot meet a communication requirement.
